RDMA_XSERVER(1)

💖 RDMA_XSERVER 💖

okay bestie, so this is rdma_xserver from the librdmacm manual, section 1 🎀 — and it is literally the RDMA CM communication server test program. yes queen, a whole server, for testing, living in your terminal. iconic behavior fr fr 💅

✨ SYNOPSIS ✨

rdma_xserver [-p port] [-c comm_type]

that's it. that's the whole vibe check. two little options and she's ready to serve 🫶

🌸 DESCRIPTION 🌸

so basically rdma_xserver uses librdmacm to set up various forms of communication and then exchange data. that's the whole job description. it establishes, it exchanges, it slays ✨ no cap.

💅 OPTIONS 💅

• -p port — this changes the port number the server listens on. by default she's posted up on port 7471. periodt.
• -c communication type — this one specifies the type of communication established with the client program. the details:
  • 'r' → results in using a reliable-connected QP, and this is the default btw, so if you don't say anything she just does this 🎀
  • 'x' → uses extended reliable-connected XRC QPs. fancy mode activated 🔥

📝 NOTES 📝

basic usage is literally: start rdma_xserver, then connect to the server using the rdma_xclient program. that's the whole group chat, both parties gotta show up 💜

🚨 okay listen, important one: because this test maps RDMA resources to userspace, users must make sure they have available system resources and permissions. this is not a drill, bestie. check the libibverbs README file for additional details — it's giving required reading, not optional 🦋
